Our History

Senior Preferred is a Medicare Advantage Health Maintenance Organization (HMO) Plan administered by Quartz Health Plan Corporation. Senior Preferred has been serving Medicare beneficiaries in our growing service area for nineteen years.

  • In 1999, Gundersen Health Plan (now Quartz Health Plan Corporation) received approval from the Centers for Medicare and Medicaid Services (CMS) to provide a Medicare Advantage (MA) product to beneficiaries in specific counties in southwest Wisconsin.
  • In 2006, we began offering MA plans with Part D (prescription drug) benefits.
  • In 2012, Senior Preferred was granted approval to expand into portions of northeast Iowa.   
  • In 2013, we began providing MA products to our neighbors across the river in three Minnesota counties.   
  • In 2017, we began serving beneficiaries in Dane and Waukesha counties. We are able to serve these new areas due to close partnerships with UW Health and ProHealth Care.   
  • In 2018, we expanded into 10 additional counties in Iowa and Wisconsin.
  • For 2019, we are excited to once again announce an expansion into Winnebago county in northern Illinois. This expansion has been made possible due to a partnership with SwedishAmerican, a division of UW Health.
